Additionally, about the major part item of invention present embodiment, set forth below, also Go for there is revolving door at arbitrary storeroom, at interior case 403, there is mounting storage box The freezer of the type of structure.
For the freezer 400 of present embodiment configured as described above, in following description, it moves Make, act on.
First, the action of kind of refrigeration cycle is described.Corresponding to the temperature of the setting in freezer, root Make kind of refrigeration cycle action according to the signal carrying out self-control device (not shown), carry out cooling operating. The cold-producing medium of the High Temperature High Pressure discharged by the action of compressor 409, (is not schemed at condenser Show) to a certain degree condensation liquefaction.And, this cold-producing medium is via being disposed in as freezer main body The side of heat insulating box 401, the back side and heat insulating box 401 before the refrigeration of scope Agent pipe arrangements (not shown) etc., prevent the water droplet ground condensation liquefaction of heat insulating box 401, arrive hair Tubule (not shown).Afterwards, in capillary tube, limit is with the suction tube to compressor 409 (not Diagram) carry out the decompression of heat exchange limit, become the liquid refrigerant of low-temp low-pressure, arrive cooler 412。
Here, in cooling chamber 410, by each storeroom that the action of blower fan 413 is collected Air, carries out heat exchange, the system in cooler 412 by cooler 412 and liquid refrigerant Cryogen evaporation gasification.Now, the air returned from storeroom, formed in cooling chamber 410 The most again cool down the cold air of each storeroom.The cold air of low temperature from blower fan 413 by distribution wind path 422, use wind path, air door to shunt, by cold room the 404, second refrigerating chamber 405, system Icehouse the 406, first refrigerating chamber 407, vegetable compartment 408 are cooled to respective purpose temperature field.
The aerofoil fan that blower fan 413 turns clockwise when being in terms of the front of freezer 400, institute By the cold air discharged to turn clockwise while with coniform flowing in the way of extending radially.Cause This, by making cold air rectification part 420a be the shape mated with the flowing discharging cold air, it is possible to no Produce whirlpool ground to be sent swimmingly to distribution wind path 422 by cold air.It addition, constituting blower fan 413 The discharge side of aerofoil fan, produce the air-flow returned at centrally directed aerofoil fan, by will On the frustum of a cone of cold air rectification part 420a, face diameter is formed as roughly the same with the wheel hub diameter of aerofoil fan Diameter, it is possible to suppress this Returning flow, it is possible to from blower fan 413 do not waste to cold air compose Blow the energy given.
The rotary shaft angulation of circular cone table top with blower fan 413 owing to discharging the formation of cold air Air flow rate, rotating speed according to blower fan 413 and different, so by changing cold air rectification part 420a The angle of taper seat, it is possible to carry out the suitableeest design according to design discharge.Such as, illustrate to make leaf The blower fan 413 of sheet footpath 90mm to 410mm to rotate before and after 1200rpm to 3000rpm, To 0.5m3/ min to 1.0m3The situation of the air quantity of/min.According to the experiment carried out with this condition, Rotary shaft is preferably 50 ° to 85 ° with the taper seat angulation of cold air rectification part 420a. Along with slowly increasing and the distance of blower fan 413 in radial direction extension, thereby, it is possible to will row The kinetic energy having going out cold air can reclaim efficiently as pressure, it is possible to do not increase blower fan 413 Power just improve discharge pressure.As shown in the embodiment, air-supply loop many at storeroom Multiple branch circuit, the parts needing to form wind path resistance as air door so in a large number wind path in, due to wind The merit of machine 413 is big, so the function that cold air rectification part 420a is played is bigger.
Along a part for the cold air of cold air rectification part 420a extension, from being arranged at cold air rectification part Upper strata outlet 420b in 420a is expelled in the first refrigerating chamber 407.Now, cold air passes through Coanda effect effect is along the power of cold air rectification part 420a.Therefore, from being arranged at cold air rectification part The cold air that hole in 420a is discharged, the frontal to blower fan 413 is smoothly discharged.Therefore, It also is able to send cold air to the front being difficult to the direct blower fan 413 sent to by cold air in prior art Reach.
It addition, the hole of upper strata outlet 420b in the central authorities being positioned at the first refrigerating chamber 407, tool There is epimere rib 420f vertical with the limit of the side away from cold air rectification part 420a, towards storeroom, So the radial composition that expands in the speed of cold air also is able to inside storeroom.Cause This, by increasing capacitance it is possible to increase is towards the cold air within the refrigerating chamber box 407b of upper strata, it is possible to the most rapidly Cooling repertory.Here, one-body molded with front partition member 420 by epimere rib 420f, energy Enough do not formed with not increasing components number, it is possible to the deviation of the wind direction caused because of solid is suppressed Must be less.And, it is possible to the deformation that can suppress in using, the structure come off are provided at a low price.
Then, the effect of rib 420e between inclined ribs 420c and chevron rib 420d, paddy is said Bright.
The cold air discharged from blower fan 413, colder than the first refrigerating chamber 407, partition member before institute The surface of first refrigerating chamber 407 side of 420 sometimes due to temperature difference and be attached with frost, ice.This frost, Ice is when using radiation heating unit 414 to heat in cooling chamber 410, through the leaf of blower fan 413 Enter between sheet in distribution wind path 422, melt because of a part for the heating installation in cooling chamber 410 Change.Freezer 400, is attached to the frost of cooler 412 and periphery thereof, ice to melt, periodically Ground interrupts cooling, heating radiation heating unit 414, thus, melts front partition member the most termly The frost on the surface of 420, ice, so there is no concern that its growth and oppressing storage space.
By such mode, the water droplet on front partition member 420 surface of thawing flows along surface Under.The water droplet that flows down arrives inclined ribs 420c, the position of chevron rib 420d, upper along each rib Surface, flows to lower (being right-hand member during inclined ribs 420c, be two ends during chevron rib 420d) respectively, So not flowing to the underface of rib.That is, utilizing inclined ribs 420c, water droplet flows to the right, so Do not flow to be positioned at upper strata outlet 420b of the underface of inclined ribs 420c.
Upper strata outlet 420b is out, in the hole of front partition member 420, to cool down the first refrigerating chamber 407 Shi Lengqi passes through, if so flowing down water droplet in upper strata outlet 420b, then in upper strata outlet 420b, water droplet is put aside in hole, it is possible to forms ice and plugging hole when cooling and causes cooling down energy Power reduces.Therefore, by arranging inclined ribs 420c, it is possible to realize can stably cooling down storage The high-quality of room.
Similarly, utilizing chevron rib 420d, water droplet flows downward from the two ends of chevron rib 420d. The width of chevron rib 420d is more than the width of lower floor's wind path 423, so from chevron rib 420d's The water droplet that two ends flow downward is flowed downward by the both sides of lower floor's wind path 423.Therefore, current Under on lower floor's wind path 423 prominent to the inner side of lower floor refrigerating chamber box 407c, it is possible to prevent from dripping Arrive down lower floor refrigerating chamber box 407c.
Lower floor refrigerating chamber box 407c is repertory accommodating container and does not have hole in bottom, if Lower floor refrigerating chamber box 407c drips, then water is put aside inside lower floor refrigerating chamber box 407c, cold But freezing time, so ice continued propagation, repertory is fixed in housing by ice, thus produces The unplessantness displeasure of the ease of use of infringement user.
Additionally, in present embodiment, be formed as structure: on front partition member 420 surface The water droplet flowed downward, the lower end of partition member 420 drops to the first refrigerating chamber 407 in the past After bottom surface, flow to lower drain pan 415, arranged outside freezer by drain pipe 416 Go out.But, by being formed as arranging the mechanism of recovery water droplet at front partition member 420, directly Falling into the structure of drain pan 415, water droplet does not drip the first refrigerating chamber 407 as storage space Bottom surface, using the teaching of the invention it is possible to provide the more freezer of high-quality.
It addition, owing to there is rib 420e between paddy between the paddy of lower floor's wind path 423, from chevron rib 420d The water conservancy of drippage attracted to rib 420e between paddy energetically by its surface tension.Therefore, it is possible to enter One step reduces the danger that the water from chevron rib 420d drippage flows to lower floor's wind path 423.
Even if additionally, between paddy rib 420e be formed without rib also have attraction the shape of effect of water, thing Matter, so the recess of similar shape, hydrophilic surface etc. can also be replaced with, it is also possible to embed it Its parts is constituted.
As it has been described above, by the effect of rib 420e between inclined ribs 420c, chevron rib 420d, paddy, It is the structure not flowing into water droplet in upper strata outlet 420b and lower floor's wind path 423.But, just in case During inflow, in the surface of upper strata outlet 420b, lower floor's wind path 423 surface produce water droplet time, Need to prevent water droplet from freezing in outlet or dripping in storage box.
Here, upper strata outlet 420b has epimere rib 420f, even if so because of temperature difference Water droplet is produced, at the water droplet of generation more top than upper strata outlet 420b in upper strata outlet 420b When wandering, it is also possible to flow under outlet 420b of upper strata along epimere rib 420f.Accordingly, it is capable to Enough prevent water droplet savings in outlet 420b of upper strata, it is provided that the freezer that quality is high.On if Section rib 420f level is constituted, and repeatedly occurs that water droplet is not wandered and cold air because discharging forms the showing of ice As, it is possible to blocking upper strata outlet 420b.
It addition, lower floor's wind path 423 has hypomere rib 423b.Upper surface at lower floor's wind path 423 Or lower floor outlet 423a periphery produces or the water droplet that drips can arrive along hypomere rib 423b Front partition member 420 surface under lower floor's wind path 423.Now, hypomere rib 423b's is following For the gradient steeper than the lower surface of lower floor wind path 423, so comparing lower floor's wind path 423 surface Water preferentially flows to hypomere rib 423b, drips it is possible to lower further along lower floor's wind path 423 Danger in lower floor refrigerating chamber box 407c.Here, by making, hypomere rib 423b's is following More than 10 ° are formed as, it is possible to more reliably water is carried out attraction and draw with horizontal plane angulation Lead.And, if hypomere rib 423b arrange interval narrow, then cold air wind path resistance increase, Reducing air-supply efficiency, increase consumption electric power, if wide, then water droplet is between hypomere rib 423b Probability under clearance flow increases, so needing the wind speed of cold air according to circulation, air quantity, storage The temperature field of room suitably sets, it is generally preferable to for 10mm~20mm.
And, the two ends, upper surface left and right of lower floor's wind path 423 form chamfering, institute with bigger R Do not flow to lower floor's outlet 423a side and readily flow to being placed in the water droplet on lower floor's wind path 423 The both sides of lower floor's wind path 423.Therefore, water droplet is upper to lower floor's wind path 423 from chevron rib 420d When falling or when producing water droplet between chevron rib 420d to lower floor's outlet 423a, also can Enough suppression water droplets drip to lower floor refrigerating chamber box 407c from lower floor's outlet 423a, it is possible under from The both sides of layer wind path 423 guide the surface to front partition member 420.
Finally, the second refrigerating chamber rib 424b is described.Will be second by the second refrigerating chamber rib 424b The water droplet that the lower surface of refrigerating chamber wind path 424 produces guides to front partition member 420 surface, energy Enough prevent from dripping in the second refrigerating chamber box 405b.Second refrigerating chamber rib 424b is cold with second Freeze the shape that the lower surface of room wind path 424 is general triangular on one side, so being ratio the below The gradient that the lower surface of two refrigerating chamber wind paths 424 is steep, so water droplet is than the second refrigerating chamber wind path 424 Preferentially flow at the second refrigerating chamber rib 424b.As long as additionally, the second refrigerating chamber rib 424b is With lower surface and the front partition member 420 shape as both sides of the second refrigerating chamber wind path 424, Can not be general triangular be trapezoidal other shape such as grade, preferably other limit with triangle time Equally, there is the gradient steeper than the lower surface of the second refrigerating chamber wind path 424.And, second is cold If freeze room rib 424b arrange interval narrow, water droplet easily keeps the most on the contrary, if wide, The probability that then water droplet easily flows down from the gap of the second refrigerating chamber rib 424b improves, it is generally preferable to For 10mm~20mm.
Second refrigerating chamber wind path 424 is positioned at the position more closer to the top than blower fan 413, so removing In frost operating, the heating installation in the cooling chamber 410 that blower fan 413 spills is discharged from upper strata further Mouth 420b is leaked to storage space, and heating installation rises, and collides with the second refrigerating chamber wind path 424.Warm Gas is turned cold by the wall of the second refrigerating chamber wind path 424, at wind path surface sweating, so second The lower surface of refrigerating chamber wind path 424 is easily with water droplet, it is possible to say the second refrigerating chamber rib The effect of 424b is the biggest.
Additionally, rib 420e between inclined ribs 420c, chevron rib 420d, paddy, epimere rib 420f, under The water removing structure of section rib 423b, the second refrigerating chamber rib etc. is not only as the second of cryogenic temperature territory Refrigerating chamber 405, ice-making compartment the 406, first refrigerating chamber 407 effectively, are easily producing temperature difference Near the cold gas exhausting outlet of other storeroom the most effective.By as required at cold room 404 Outlet, the outlet of vegetable compartment 408 are also provided with rib, it is possible to prevent cold room shelf 404c, Cold room box 404d, upper strata vegetable compartment box 408b equivalance water-retention are dripped, moistening repertory.
As it has been described above, in present embodiment, upper strata outlet 420b and lower floor's outlet 423a, Second refrigerating chamber outlet 424a is provided with inclined ribs 420c prevented under water droplet, chevron at periphery Rib 420e, epimere rib 420f, hypomere rib 423b, the row of the second refrigerating chamber rib between rib 420d, paddy Water-bound.Thereby, it is possible to by outlet periphery produce water droplet or above outlet stream come Water droplet is avoided outlet and is guided to outlet, prevents in outlet it is possible to provide Delay and the freezer of the high-quality dripped to mounting parts.
And, be there is the width of the width more than lower floor's outlet 423a by chevron rib 420d, The water droplet formed above lower floor's outlet 423a, avoids lower floor's wind along chevron rib 420d Drip downwards about road.Therefore, it is possible to suppression drops down onto lower floor's refrigerating chamber from lower floor's wind path 423 Box, it is possible to provide not at high-quality cold of lower floor refrigerating chamber box savings of mounting repertory Zang Ku.Now, chevron rib 420d is arranged at from lower floor's outlet 423a separation, the stream of cold air Dynamic position slowly, it is possible to prevent from becoming wind path resistance and damaging air-supply efficiency, it is possible to press down System consumes the increase of electric power.
And, the upper surface of inclined ribs 420c is formed as the rectilinear form hung down in the minimum bottom right of right-hand member, The upper surface of chevron rib 420d has the chevron shape that two ends, left and right are minimum.Thus, discharge on upper strata The water droplet that the top of mouth 420b and lower floor's outlet 423a generates is wandered to each rib, not respectively Rib is put aside and is flowed to lower part immediately, the most just flows along front partition member 420 surface Fall.Therefore, it is possible to prevent water droplet from crossing each rib from just towards cold gas exhausting outlet at each rib savings Fall, it is possible to reduce due to ice blockage upper strata outlet 420b further, or freezing in lower floor The danger of water droplet savings in the box of room.
This effect can be by the angle making the upper surface of each rib have with respect to the horizontal plane more than 5 ° Degree, improves flowing the most swimmingly.
It addition, upper strata outlet 420b, lower floor's outlet 423a, the second refrigerating chamber outlet 424a Its periphery have guiding rib 420e between the epimere rib 420f of flowing of water, hypomere rib 423b, paddy, Second refrigerating chamber rib 424b.Thus, outlet periphery produce or stream come water droplet do not inhaled Cause outlet and be attracted to each rib, along the side's diffluence further downward of each rib.Therefore, press down Controlling the water circulation drops in outlet savings or drops down onto mounting parts from outlet, it is possible to provide high-quality Freezer.
It addition, rib 420e is arranged at the lower section periphery at the two ends of chevron rib 420d between paddy.Thus, The water droplet avoiding lower floor's wind path 423 at left and right directions and flow down from the two ends of chevron rib 420d, i.e. Make water droplet up assemble its amount is many or trend strong in the case of, also due to be attracted between paddy Rib 420e is so along rib 420e flowing between paddy.Therefore, it is possible to will leave from chevron rib 420d Water droplet again to lower floor's wind path 423 flowing danger be suppressed to Min..
It addition, rib 420e is and the front integrated rib of partition member 420 between paddy.Thus, no Increase components number just can reliably be guided to outlet by water droplet, so rib between paddy 420e deforms in the use of freezer 400, comes off less.Therefore, it is possible to provide energy at a low price The freezer of the high-quality of enough high states keeping quality during use.
Epimere rib 420f and hypomere rib 423b is and upper strata outlet 420b and lower floor's outlet The rib that the bottom and upper segment of 423a connects.Thus, the water droplet wandered in outlet will not put aside in Outlet or from it separation drop down onto lower floor refrigerating chamber box 407c, and directed along each rib To outlet.Reduce due to ice blockage upper strata outlet further therefore, it is possible to provide 420b or the freezer of dangerous high-quality dripped in lower floor's refrigerating chamber box inner product water-retention.
It addition, lower floor's wind path 423 and the second refrigerating chamber wind path 424 are respectively under lower surface has Section rib 423b and the second refrigerating chamber rib 424b.Thus, the water droplet edge of the lower surface to wind path is wandered Rib and discharge the front end guidance of wind path to bottom from cold air.Therefore, it is possible to prevent from outlet week Drip lower floor refrigerating chamber box 407c or the second refrigerating chamber box in the cold air discharge wind path leading section on limit 405b, using the teaching of the invention it is possible to provide the freezer of high-quality.
It addition, hypomere rib 423b's and the second refrigerating chamber rib 424b compares lower floor's wind path 423 below Big angle is with respect to the horizontal plane formed with the lower surface of the second refrigerating chamber wind path 424.Thus, The water droplet of diffluence can draw than wind path lower surface more along the following flowing of rib it is possible to utilize The portion that leads reliably guides water droplet.
Now, formed by the following and horizontal plane of hypomere rib 423b and the second refrigerating chamber rib 424b Angle is more than 10 °, it is possible to draw the water droplet of diffluence the most swimmingly along guide portion Lead.Therefore, it is possible to suppression is to lower floor refrigerating chamber box 407c, the second refrigerating chamber box 405b further Drip.
(the 5th embodiment)
